Description

この発明は、回路基板に実装して使用する端子台に関し、特に、回路基板に実装されるコイル等の各種電子部品に大電流（例えば５０Ａ以上）を流すために用いる端子台に関する。   The present invention relates to a terminal block mounted on a circuit board and used, and more particularly to a terminal block used to flow a large current (for example, 50 A or more) to various electronic components such as coils mounted on the circuit board.

従来より、回路基板に、例えばコイルやコンデンサ等の各種電子部品を実装してノイズフィルタを構成すること等が行われている。尚、上記ノイズフィルタは、電源ライン或いは通信ライン等の外部ラインを経由して電子機器内に侵入する各種のノイズによって、電子機器が誤動作することを防止し、また、電子機器が発生するノイズを外部に発散させないために使用されるものである。   Conventionally, a noise filter is configured by mounting various electronic components such as a coil and a capacitor on a circuit board. The noise filter prevents the electronic device from malfunctioning due to various types of noise entering the electronic device through the external line such as the power supply line or the communication line, and the noise generated by the electronic device It is used to prevent it from being emitted outside.

上記回路基板には、電子部品同士の接続や電子部品への通電を行うための導体パターンが形成されているが、常用されている導体パターンの厚さは３５μｍ程度と非常に薄いため、導体パターンを介してコイル等の電子部品に大電流を通電すると導体パターンが発熱・高温化するため、流せる電流には限界があり、３０Ａ程度が限度であった。   The circuit board is provided with a conductor pattern for connecting electronic components to each other and energizing the electronic components. However, since the thickness of a commonly used conductor pattern is as thin as about 35 μm, the conductor pattern When a large current is applied to an electronic component such as a coil via the conductor pattern, the conductor pattern generates heat and heats up, so the current that can be supplied has a limit, and the limit is about 30 A.

このため、図２０及び図２１に例示するように、従来、回路基板70に実装されたコイル72に大電流（例えば５０Ａ以上）を通電する場合、コイル72の導線74の先端部を、圧着端子76の嵌合部76ａに挿通して圧着接続すると共に、回路基板70を貫通するボルト78に螺合させた一対のナット80，82間に配置されるように上記圧着端子76のリング部76ｂをボルト78に接続している。尚、図示は省略するが、コイル72の導線74の先端部と圧着端子76の嵌合部76ａとを圧着接続した後、接続強度を高めるため接続箇所は半田接合される。また、図２１において、84，86はワッシャである。
そして、図示しない外部電源線を、一対のナット80，82間に接続した上で、斯かる外部電源線を介してコイル72に大電流を供給していた。 For this reason, as illustrated in FIGS. 20 and 21, conventionally, when a large current (for example, 50 A or more) is applied to the coil 72 mounted on the circuit board 70, the tip of the lead wire 74 of the coil 72 is connected to the crimp terminal. The ring portion 76 b of the crimp terminal 76 is disposed between the pair of nuts 80 and 82 screwed to the bolt 78 penetrating the circuit board 70 while being inserted through the fitting portion 76 a of the 76 and crimped and connected. Connected to bolt 78. Although illustration is omitted, after the tip end portion of the conducting wire 74 of the coil 72 and the fitting portion 76a of the crimp terminal 76 are crimped and connected, the connection portion is soldered to increase the connection strength. In FIG. 21, 84 and 86 are washers.
Then, after an external power supply line (not shown) is connected between the pair of nuts 80 and 82, a large current is supplied to the coil 72 through the external power supply line.

図２０及び図２１に示す方法にあっては、回路基板70の導体パターンを介在させずにコイル72に電流を供給するので、大電流を流すことができるのである。   In the method shown in FIGS. 20 and 21, since the current is supplied to the coil 72 without interposing the conductor pattern of the circuit board 70, a large current can flow.

しかしながら、上記従来方法にあっては、
（１）コイル72の導線74の先端部に接続する圧着端子76が必要であると共に、導線74と圧着端子76との半田接合が必要であり、また、
（２）作業者は、ボルト78を締結するためのドライバーの他に、ナット80，82の締付工具が必要であり、さらに、
（３）ナット80，82が２個あるため締付工数が多くなる
等、部品点数の増加及び作業工程の煩雑化を招来していた。 However, in the above conventional method,
(1) The crimp terminal 76 connected to the tip of the lead 74 of the coil 72 is required, and the solder connection between the lead 74 and the crimp terminal 76 is also required,
(2) The operator needs a tightening tool for the nuts 80 and 82 in addition to the screwdriver for fastening the bolt 78.
(3) Since there are two nuts 80 and 82, the number of tightening steps increases, resulting in an increase in the number of parts and complication of the working process.

本発明は、従来の上記問題点に鑑みて案出されたものであり、その目的とするところは、簡易な構成で回路基板に実装される電子部品に大電流を流すことのできる端子台を実現することにある。   The present invention has been made in view of the conventional problems described above, and the object of the present invention is to provide a terminal block capable of flowing a large current to an electronic component mounted on a circuit board with a simple configuration. It is about to realize.

また、天板部のネジ用孔には標準ネジを挿入できるので、該標準ネジと螺合する標準ナットと併用することにより、ドライバーのみで接続作業を行うことができる。 In the terminal block according to the present invention, a top plate portion in which a screw hole into which a standard screw is inserted is formed, and a lead connection plate in which at least the same number of lead insertion holes are formed. Because it is equipped with a part, it is easy to connect the lead wire of the electronic component to be connected directly to the lead wire insertion hole of the lead wire connection plate part and connect the external power line to the standard screw inserted into the screw hole of the top plate part With this configuration, a large current can be passed through the electronic component without interposing the conductor pattern of the circuit board.
Further, since a standard screw can be inserted into the screw hole of the top plate portion, connection work can be performed only with a driver by using it together with a standard nut screwed with the standard screw.

また、脚部に天板部の内方側に向かって突出する突起を形成し、標準ネジを、上記天板部の表面側からネジ用孔に挿通すると共に、天板部の裏面側において上記標準ネジと標準ナットを螺合した場合に、脚部に形成した上記突起が、標準ナットと当接して回動を規制するよう構成したので、標準ナットが回動して生じる緩みを防止することができる。 In addition, a protrusion that protrudes inward of the top plate portion is formed on the leg portion, and a standard screw is inserted into the screw hole from the front surface side of the top plate portion, and on the back side of the top plate portion.

A leg portion 14 of the book and a substantially L-shaped lead wire connecting plate portion 16 extending outward from one end portion of the top plate portion 12 and having two lead wire insertion holes 16a are formed.
In addition, a protrusion 14 a that protrudes inward of the top plate 12 is formed in the middle of each leg 14.

図１０〜１５に示すように、本発明の端子台10には、日本工業規格（ＪＩＳ規格）に適合する汎用市販品の標準ネジ18及び標準ナット20が取付けられる。
すなわち、ドライバー用の十字穴付きネジより成る標準ネジ18を、天板部12の表面側からネジ用孔12ａに挿通し、天板部12の裏面側に配置させた六角ナットより成る標準ナット20に標準ネジ18の軸を螺合している。
尚、標準ネジ18と天板部12の表面との間には、スプリングワッシャー22とワッシャー24が配置されている。 As shown in FIGS. 10 to 15, general-purpose commercially available standard screws 18 and standard nuts 20 that conform to Japanese Industrial Standards (JIS standards) are attached to the terminal block 10 of the present invention.
That is, a standard screw 18 consisting of a screw with a cruciform hole for a driver is inserted into the screw hole 12 a from the surface side of the top plate 12 and is arranged on the back side of the top plate 12. The shaft of the standard screw 18 is screwed into the screw.
A spring washer 22 and a washer 24 are disposed between the standard screw 18 and the top plate 12.

図１３に示すように、天板部12の裏面側において、標準ネジ18と標準ナット20を螺合させた場合に、端子台10の脚部14に形成した突起14ａが、角ナットである六角ナットより成る標準ナット20の角部と当接して回動を規制するよう構成されており、標準ナット20が回動して生じる緩みを防止できるようになっている。   As shown in FIG. 13, when the standard screw 18 and the standard nut 20 are screwed together on the back side of the top plate 12, the protrusion 14a formed on the leg 14 of the terminal block 10 is a hexagon that is a square nut.

また、上記標準ネジ18として、十字穴付きネジの他、マイナス穴付きネジを使用しても勿論良い。 The standard nut 20 may use a polygonal nut such as a square nut or a round nut other than the hexagonal nut, and in this case also, the terminal block when the standard screw 18 and the standard nut 20 are screwed together. The protrusions 14a formed on the ten leg portions 14 are configured to abut against the standard nut 20 and restrict rotation.

次に、図１６〜図１９に基づいて、本発明に係る端子台10を回路基板26に取付けて使用する場合について説明する。
図１６は本発明の端子台10を回路基板26に取付けた状態を示す平面図、図１７は同部分拡大斜視図、図１８は同部分拡大正面図、図１９は同部分拡大左側面図であり、本発明に係る端子台10と、回路基板26に実装した電子部品としてのコイル28の導線30との接続を行った場合を例示している。 Next, a case where the terminal block 10 according to the present invention is used by being attached to the circuit board 26 will be described with reference to FIGS.
16 is a plan view showing a state in which the terminal block 10 of the present invention is attached to the circuit board 26, FIG. 17 is an enlarged perspective view of the same part, FIG. 18 is an enlarged front view of the same part, and FIG. The case where the connection between the terminal block 10 according to the present invention and the conductor 30 of the coil 28 as an electronic component mounted on the circuit board 26 is illustrated.

上記コイル28は、電源線等を通じるノイズを遮断・低減するためのノイズフィルタの構成部品等として広く用いられているものであり、図１６に示すように、磁性材料より成るコアを内蔵したリング状のコア内蔵ケース32の外周面に、可撓性を有する銅等より成る２本組の導線30をバイファイラ巻きして成るものである。   The coil 28 is widely used as a component or the like of a noise filter for blocking and reducing noise passing through a power supply line or the like, and as shown in FIG. 16, a ring incorporating a core made of a magnetic material A pair of conducting wires 30 made of copper or the like having flexibility are wound around the outer peripheral surface of a case 32 with a built-in core by bifilar winding.

本発明の端子台10は、回路基板26に形成した孔（図示省略）に、４本の脚部14を挿通することにより回路基板26に取付けられる。尚、標準ネジ18の先端は、回路基板26に形成した孔（図示省略）内に収納される。
尚、図１８及び図１９に示すように、回路基板26の孔に４本の脚部14を挿通した場合に、標準ナット20の底面が回路基板26の表面に当接するように成されており、端子台10の天板部12と回路基板26との間で標準ナット20を強固に固定できる。 The terminal block 10 of the present invention is attached to the circuit board 26 by inserting the four legs 14 into holes (not shown) formed in the circuit board 26. The tip of the standard screw 18 is accommodated in a hole (not shown) formed in the circuit board 26.
As shown in FIGS. 18 and 19, the bottom surface of the standard nut 20 is in contact with the surface of the circuit board 26 when the four leg portions 14 are inserted into the holes of the circuit board 26. The standard nut 20 can be firmly fixed between the top plate 12 of the terminal block 10 and the circuit board 26.

上記コイル28は、コア内蔵ケース32の外周面に２本組の導線30をバイファイラ巻きして成ることから、回路基板26に固定された各端子台10にはそれぞれ２本の導線30が接続されるものであり、図１７に示すように、端子台10の導線接続板部16に形成された２個の導線挿入孔16ａに導線30が挿通され直接接続されている。   The coil 28 is formed by bifilar winding two conductors 30 around the outer peripheral surface of the case 32 with a built-in core. Therefore, two conductors 30 are connected to each terminal block 10 fixed to the circuit board 26. As shown in FIG. 17, the lead wire 30 is inserted directly into the two lead wire insertion holes 16a formed in the lead wire connection plate portion 16 of the terminal block 10. As shown in FIG.

尚、導線接続板部16の導線挿入孔16ａに挿通接続された導線30は、回路基板26に形成した孔（図示省略）を通って回路基板26の裏面側に引き出されている（図１８及び図１９参照）。
回路基板26の裏面側に引出された端子台10の脚部14及び導線30は、図示しない半田を介して回路基板26と接続される。半田接続対象の脚部14及び導線30が、回路基板26の裏面側に引出されているので、自動半田ディップ（溶融した半田を貯溜する半田槽に回路基板26の半田付面を侵漬して半田付けする方法）で半田付けすることができる。 The conducting wire 30 inserted and connected to the conducting wire insertion hole 16a of the conducting wire connection plate portion 16 is drawn out to the back surface side of the circuit board 26 through a hole (not shown) formed in the circuit board 26 (FIG. 18 and FIG. See Figure 19).
The leg portion 14 and the lead 30 of the terminal block 10 drawn out on the back surface side of the circuit board 26 are connected to the circuit board 26 via a solder (not shown). Since the legs 14 and the conductors 30 to be soldered are drawn out to the back side of the circuit board 26, the automatic solder dip (the soldered surface of the circuit board 26 is absorbed in the solder tank for storing the melted solder) Soldering method).

図示しない外部電源線は、端子台10に挿通された標準ネジ18とスプリングワッシャー22間に接続され、この結果、上記外部電源線を介してコイル28に５０Ａ以上の大電流を流すことができる。   An external power line (not shown) is connected between the standard screw 18 inserted into the terminal block 10 and the spring washer 22, and as a result, a large current of 50 A or more can flow through the coil 28 through the external power line.

上記においては、端子台10の導線接続板部16に２個の導線挿入孔16ａを形成した場合を例示したが、これは端子台10に接続するコイル28の導線数（２本）に対応させたからであり、これに限定されるものではない。
例えば、端子台10に接続する電子部品の導線の数が３本の場合には、導線接続板部16に少なくとも３個の導線挿入孔16ａを形成しておけば良い。尚、導線挿入孔16ａの数が、電子部品の導線の数より多い分には、使用しない導線挿入孔16ａが存在するだけで特に問題は生じない。
従って、端子台10の導線接続板部16には、接続対象の電子部品の導線の数と、少なくとも同数の導線挿入孔16ａが形成されていれば良い。 In the above, the case where the two conductor insertion holes 16a are formed in the conductor connecting plate portion 16 of the terminal block 10 is illustrated, but this corresponds to the number of conductors (two) of the coil 28 connected to the terminal block 10. For this reason, the present invention is not limited to this.
For example, when the number of conductors of the electronic component connected to the terminal block 10 is three, at least three conductor insertion holes 16 a may be formed in the conductor connection plate portion 16. Incidentally, when the number of the lead wire insertion holes 16a is larger than the number of the lead wires of the electronic component, there is no particular problem as long as the lead wire insertion holes 16a are not used.
Therefore, in the conductor connection plate portion 16 of the terminal block 10, at least the same number of conductor insertion holes 16a may be formed as the number of conductors of the electronic component to be connected.

本発明に係る上記端子台10にあっては、標準ネジ18が挿入されるネジ用孔12ａが形成された天板部12と、接続対象のコイル28の導線30の数と同数の導線挿入孔16ａが形成された導線接続板部16を備えているので、接続対象のコイル28の導線30を導線接続板部16の導線挿入孔16ａに直接接続すると共に、天板部2のネジ用孔12ａに挿入した標準ネジ18に外部電源線を接続するという簡易な構成により、回路基板26の導体パターンを介在させることなく、コイル28に大電流を流すことができる。
また、天板部12のネジ用孔12ａには標準ネジ18を挿入できるので、該標準ネジ18と螺合する標準ナット20と併用することにより、ドライバーのみで接続作業を行うことができる。 In the terminal block 10 according to the present invention, the number of conductor insertion holes equal to the number of conductors 30 of the top plate portion 12 in which the screw holes 12a into which the standard screws 18 are inserted and the coils 28 to be connected are formed. Since the conductor connection plate portion 16 formed with 16a is provided, the conductor 30 of the coil 28 to be connected is directly connected to the conductor insertion hole 16a of the conductor connection plate portion 16 and the screw hole 12a of the top plate 2 A simple configuration in which an external power supply line is connected to the standard screw 18 inserted in can allow a large current to flow in the coil 28 without interposing the conductor pattern of the circuit board 26.
Further, since the standard screw 18 can be inserted into the screw hole 12a of the top plate portion 12, by using it together with the standard nut 20 screwed with the standard screw 18, the connection work can be performed only with a screwdriver.
